Vibhor Kumar: Exploiting SQL/JSON Enhancements for Modern Workloads in PostgreSQL 16
The latest iteration of PostgreSQL, version 16, brings a suite of enhancements that bolster its capabilities with JSON data. These improvements not only align PostgreSQL more closely with the SQL/JSON standard but also offer significant optimizations that streamline and enhance working with JSON data. This evolution is a testament to PostgreSQL’s commitment to meeting the demands of modern, data-driven applications that leverage semi-structured data for a myriad of use cases.

Andrew Dunstan: Review: PostgreSQL 16 Administration Cookbook
This book, published in December 2023 by packt, is the latest incarnation of a book originally principally authored by Simon Riggs, and brought up to date for PostgreSQL 16 by my EDB colleagues Gianni Ciolli, Boriss Mejías, Jimmy Angelakos and Vibhor Kumar. It's available in both hard copy and electronic format. For review purposes, the publisher provided me with one of each. DBAs will probably find the electronic format more useful because of the ability to cut and paste from it.

Jan Karremans: The four quadrants of an Oracle migration
The missing pieceWhen you think about migration from Oracle to Postgres, most people just say that it is easy. And if you consult the various sources of information, nothing tells you differently.
And it might not even be untrue. Most databases we create, manage, and run are easy to migrate. If you look at the characteristics of these databases, the large bulk of these:
Dian Fay: (Plausible) Random Geography Generation with PostGIS: Fluviation
Welcome to Squaria.
Squaria is a continent of highly unstable geography defined by a single SQL query (with, as we'll see, many, many CTEs). Its only consistent properties at the moment are its boxy shape and the two unnervingly straight mountain ranges that cross its breadth and meet on its lower eastern edge. Those mountains are impossible, but today's topic is fluviation, that is, rivers and riverine lakes; we'll see about plausible plate tectonics some other time, maybe.
Ryan Lambert: Hosting a set of Postgres Demo databases
In April 2023, I submitted my proposal for a full-day pre-conference at PASS 2023. My chosen topic was focused on PostGIS, titled GIS Data, Queries, and Performance. A key part of my submission was that the session would be an interactive, follow-along type design. Julie and I believe that doing is key to learning so we wanted to enforce that as much as possible.
Luca Ferrari: pgagroal-cli gains JSON output
A new feature of pgagroal-cli that now makes another step towards the full automation.
pgagroal-cli gains JSON outputAt last, I made it: a commit in pgagroal to support JSON output. It has been quite hard and long, not for the technological challenge, rather for all the little details like continuos integration, to get this work completed. As a rule of thumb, I stated this work last November (of course, slowly working in and out).
David Z: Enhance PostgreSQL TLS Security with OCSP Stapling
In my previous blog, I discussed how to quickly set up a TLS connection between a PostgreSQL server and a psql client. In this blog, I will guide you through the process of setting up a TLS connection using OCSP Stapling, which can help improve the security of PostgreSQL.
2. What is OCSP Stapling?Before diving into how to enable OCSP Stapling with PostgreSQL, we need to understand some basic concepts:

My colleague Bob Pacheco asked me to help with a strange problem he was witnessing for a client. A new Postgres cluster was getting created on a Kubernetes node, but it refused to start.
Stefan Fercot: Back from FOSDEM 2024
Everyone knows FOSDEM, right?
The PostgreSQL Project has been present there with a booth and a Devroom since more than 15 years now!
And this year there was the 10th FOSDEM PGDay organized on the Friday before FOSDEM.
I had the chance to spend 3 days with awesome #PostgresFriends and even more free and open source software aficionados.
Here’s a short writing of how I lived those exhausting but very exciting days.
Pavel Stehule: new extension pgmeminfo
I wrote very simple extension pgmeminfo for PostgreSQL12+, that should to help with investigation of memory usage by Postgres. Function pgmeminfo returns glibc information about memory usage provided by function mallinfo(). It is much more precious than usage top or htop.

David Rowley: What’s new in the Postgres 16 query planner / optimizer
PostgreSQL 16 introduces quite a few improvements to the query planner and makes many SQL queries run faster than they did on previous versions of PostgreSQL.
If you look at the PG16 release notes, you’ll see some of these planner improvements. But with the volume of changes made in each PostgreSQL release, it’s not possible to provide enough detail about each and every change. So maybe you might need a bit more detail to know what the change is about—before you understand if it’s relevant to you.
